Ok, America, how hard is it to keep track of what you eat? Because between calorie menus and Apple Dippers this obesity problem should really be going away. Unfortunately it's not, but for those who can afford iPhones and would like to watch what they eat, there's Meal Snap: an app that will calculate your meal's calories based on a photograph. "Auto-magically!" (Ugh.)

Meal Snap has a database of about 350,000 meals and snacks, but even with that it's tough to get an accurate reading. A "salad and chicken nuggets" ranges from 107 calories to 406, so your estimated caloric intake could be off by hundreds of calories a day. And one commenter writes on MobileCrunch, "So can I hide all the sausages and chocolate bars under an even coating of green salad and then take a picture of it from a remote distance so that the program thinks it’s just a small portion of salad?" Brilliant! Finally, you can enjoy your sausage and chocolate salad without your iPhone giving you all that guilt.

New Yorkers are an informed bunch, so the $2.99 app may not be the smartest investment. Then again, think of how much fun you could have tricking it when you eat at wd-50!
